The Ford Mustang was brought out five months before the normal start of the 1965 production year. The earliest versions are often referred to as 1964½ models, but VIN coded by Ford and titled as 1965 models with production beginning in Dearborn, Michigan on March 9, 1964 and the new car was introduced to the public on April 17, 1964 at the New York World's Fair.

From 1967 until 1973, the Mustang got bigger but not necessarily more powerful. The revised Mustang retained the original body structure but styling was refreshed, giving the Mustang a more massive look overall. Front and rear end styling was more pronounced, and the "twin cove" instrument panel offered a thicker crash pad, and larger gauges. Hardtop, fastback and convertible body styles continued as before. Federal safety features were standard that year, including an energy-absorbing steering column and wheel, 4-way emergency flashers, and softer interior knobs.
